Who doesn’t want to make a beautiful map? Aside from a catchy title, this tutorial by Boris Müller goes into detail on how he and Fabian Ehmel created a lovely butterfly projection map. You’ll find out all the tools they used, the data, as well as the process to get to the final result you can see above.
Most of the detail is lost in the tiny image on this newsletter, I recommend having a read of the original post and looking at the high-resolution map as it’s really good.
